investigations on dry sliding wear behavior of in situ casted aa7075 tic metal matrix composites by using taguchi technique
Materials & Design, 2014Co-Authors: S Baskaran, V. Anandakrishnan, Muthukannan DuraiselvamAbstract:Abstract High strength 7075 aluminum matrix composites with 4 and 8 wt.% of TiC particulate reinforcement was synthesized by reactive in situ casting technique. X-ray diffraction analysis and scanning electron microscopy were used to confirm the presence of TiC particles and its uniform distribution over the aluminum matrix. The dry sliding wear behavior of the as-casted composites was investigated based on Taguchi L 27 orthogonal array experimental design to examine the significance of reinforcement quantity, load, sliding velocity and sliding distance on wear rate. The combination of 4 wt.% of TiC, 9.81 N load, 3 m/s sliding velocity and 1500 m sliding distance was identified as the optimum blend for minimum wear rate using the Main Effect Plot. Load and sliding velocity were identified as the highly contributing significant parameters on the wear rate using ANOVA analysis. Further a confirmation test was also conducted with the optimum parameter combination for validation of the Taguchi results.

With this technique, the Inconel 718 material was fabricated in three different build orientations (horizontal, vertical, and angular). Further, the fabricated samples subjected to a heat treatment process as per the standards. Samples from the fabricated material were analyzed through the X-ray diffraction technique and scanning electron microscope analysis. Dry sliding wear test was conducted with Taguchi’s orthogonal design, and the coefficient of friction was considered as the response. Best parameter combination to obtain the minimum coefficient of friction was identified with the Main Effect Plot. The significant parameter which affects the response was identified through the analysis of variance.

Tribological behavior of AA7075-TiC composites by powder metallurgy
Industrial Lubrication and Tribology, 2018Co-Authors: C Saravanan, Veeramani Anandakrishnan, K. Subramanian, S SathishAbstract:Purpose Aluminium is the most preferred material in engineering structural components because of its excellent properties. Furthermore, the properties of aluminium may be enhanced through metal matrix composites and an in-depth investigation on the evolved properties is needed in view of metallurgical, mechanical and tribological aspects. The purpose of this study is to explore the Effect of TiC addition on the tribological behavior of aluminium composites. Design/methodology/approach Aluminium metal matrix composites at different weight percentage of titanium carbide were produced through powder metallurgy. Produced composites were subjected to sliding wear test under dry condition through Taguchi’s L9 orthogonal design. Findings Optimal process condition to achieve the minimum wear rate was identified though the Main Effect Plot. Sliding velocity was identified as the most dominating factor in the wear resistance. Practical implications The production of components with improved properties is promoted efficiently and economically by synthesizing the composite via powder metallurgy. Originality/value Though the investigations on the wear behavior of aluminium composites are analyzed, reinforcement types and the mode of fabrication have their significance in the metallurgical and mechanical properties. Thus, the produced component needs an in-detail study on the property evolution.

Investigation on the abrasive water jet machinability of AA2014 using SiC as abrasive
Materials Today: Proceedings, 2019Co-Authors: R. Shibin, S Sathish, V. Anandakrishnan, Vinod Mallemala SujanaAbstract:Abstract Aluminium alloy AA2014 was subjected to abrasive water jet machining with the abrasive particle as silicon carbide. Though several parameters are there, the most critical parameters such as traverse speed, pressure, mass flow rate and standoff distance was considered for machining. The selected parameters were varied at three levels, and an L9 orthogonal design was developed. Based on the developed design, the abrasive water jet cutting was performed on the aluminium alloy, and the depth of cut was measured and analysed using Taguchi's quality characteristic “Larger the better”. The optimum parameter to realize a higher depth of cut was identified using the Main Effect Plot. Also, the parameter which has a greater stimulus on the depth of cut was identified using response table and analysis of variance.
